THOMAS E. AINLEY, OF UXBRIDGE, MASSACHUSETTS.

CARDlNG-iVlA-CHINE.

Specification of Letters Patent.

Patented. May 14,1907.

Application filed April 23,1906. Serial No. 313,260.

To all whom it may concern.-

Be it known that I, THOMAS E. AINLEY, a citizen of the United States, residing at UK- bridge, in the county of Worcester and State of Massachusetts, have invented new and useful Improvements in Carding-Machines, of which the following is a specification.

My invention pertains to carding machines 7 and more particularly to means for stripping the doffer rolls thereof; and it contemplates the provision in a carding machine, of highly efficient stripping mechanism which requires but little attention while in operation and is constructed with a view of withstanding wear and at the same time prolonging the usfifulnessof the card clothing on the various ro s.

With the foregoing objects inmindthe invention will be fully understood from the following description and claim when the same are read in connection with the accompanying drawings, forming a part of this specification, in which:

Figure 1 is a detail elevation of one side of a carding machine equipped with the present and preferred embodiment of my invention.

Fig. 2 isa top plan view of the machine. Fig.

3 1s a view similar to Fig. 1 of the opposite side of the machine.

Similar letters designate corresponding parts in all of the views of the drawings, referring to which:

A is the main frame of the machine which may be of the ordinary construction or of any other construction compatible with my invention, and B is the main cylinder which is preferably of the type usually employed for carding wool.

C is the top doffer roll of the machine, and D is the bottom doffer roll. These dofier rolls each have a shaft a and rings 1) of card clothing, and they are so relatively arranged that the card clothing rings 6 of one roll rest in the same vertical planes as the circumferential spaces between the card clothing rings of the other roll, this in order to enable the two rolls to thoroughly doff the cylinder B from end to end thereof. The shafts a of the doifer rolls are journaled in suitable bearings in the main frame A, and the card clothing of the rolls is designed to work against that of the cylinder B after the manner shown in Figs. 1 and 3.

E is a stripper roll arranged to cooperate with the top doffer roll 0, and F is a stripper roll arranged to cooperate with'the bottom doffer roll D. Each of the stripper rolls is covered with a filleting or card clothing, and rotation of the said rolls in the direction indicated byarrows is produced through driving connections which form no part of my invention and which I have therefore deemed it unnecessary to illustrate.

G is a top clearer roll, and H is a bottom clearer roll. ered with card clothing, and the roll G is designed to be rotated in the direction indicated by arrow by the train of gearing between. the same and the upper stripper roll E, while theroll H is designed to be similarly rotated through the medium of the train of gears illustrated by which it is connected with the lower or bottom stripper roll F. Moreover it will be noticed that the points of the clothing on the stripper rolls and the points of the clothing on the doffer rolls are intermeshed to a slight extent which assures thorough dofiing, and the points of the clothing on the stripper rolls are also intermeshed to a slight extent with the points of the clothing on the clearer rolls, this latter in order to These rolls G and H are covenable the rolls G and H to perfectly clear the I stripper rolls, and in that way adapt the inachine to operate properly for a considerable time with little or no attention. I also desire it understood. that in order to increase the efiiciency of the machine, the speed of the stripper rolls at the peripheries thereof should be a little faster than the speed of the peripheries of the doffer rolls, while the speed of the clearer rolls at their peripheries should be faster than the speed of the peripheries of the stripper rolls. p

I I are top rub aprons, and J J are bottom rub aprons. These aprons I and J are designed to be'driven in the directions indicated by arrows through connections which are not comprised in my invention and are therefore not illustrated. The function of the said aprons is to receive the sliver from the stripper rolls, and make the same into roving. In this connection I desire to state that while I prefer to employ the clearer rolls G and H in connection with the stripper rolls E and F, the said clearer-rolls are not essential to the successful operation of the machine and may therefore be omitted when desired without involving a departure from the scope of my claimed invention. I also desire it understood that means other than the IIO rub apr ons may be employed to take the sliver from the stripper roll without departure from my invention.

The shaft of the up er stri per roll is provided at one side of t e macfiine with a eircumferentially grooved wheel K, and the shafts of both stripper rolls and both clearer rolls are provided at the opposite side of the machine with circumferentially grooved wheels L. The grooves of these latter wheels are engaged by the arms of an upright swinging or oscillatory frame M which is arranged to rock to and fro on a bearing N suitably connected to one side of the main frame A, as best shown in Fig. 2. When the frame M is oscillated it will be apparent that the stripper rolls and clearer ro ls are moved endwise to and fro, this being materially advantageous inasmuch as it prevents uneven wearing of the card clothing on the various rolls, and in that way materially prolongs the usefulness of the card clothing. The rub aprons I and J are preferably, though not necessarily, moved to and fro inde endent of and faster than the stripper and c earer rolls.

In order to oscillate the frame M and move the stripper and clearer rolls endwise to and fro I prefer to employ the mechanism best shown in Figs. 1 and 2. This mechanism comprises a worm gear a fixed on the shaft a of the upper doffer roll 0, a horizontally disposed worm gear (Z mounted on the main frame A in mesh with the gear 0 and bearing a stud e, and a lever f having one of its arms slotted to receive the stud e and its other arm disposed in the circumferential groove of the wheel K on the upper stripper roll E, virtue of this construction it will be apparent that when the doffer roll C is rotated, the stripper roll E will be moved endwise to and fro and with it the oscillatory frame M, the other stripper roll F and the clearer rolls G and H.

In the practical operation of my improve ments, the sliver is taken from the main eyl inder B by the doffers C and D, and is taken from the said doffers or do'ller rolls by the stripper rolls E and F from which it passes to the rub aprons I and J between which it is made into roving and from which it passes on to large spools (not shown).

It will be gathered from the foregoing that notwithstanding the high efficiency of my improvements, the same are simple and inexpensive in construction and embody no delicate parts such as are likely to get out of order after a short period of use.

The clearer rolls as their name implies serve to keep the stripper rolls or rather the card clothing thereof clean, and hence it will be appreciated that my improvements require but a minimum amount of attention while in operation.

I prefer to employ two dofler rolls and stripper rolls and clearer rolls complen'ientary to said doffer rolls.

Having described my invention, what I claim and desire to secure by Letters-Patent, is:

In a carding machine the combination of lower and upper doffer rolls; one of said rolls being provided on its shaft with a worm. gear, lower and upper stripper rolls movable to and fro in the direction of their length, a swinging frame engaging the stripper rolls at one end thereof, a circumferentially-grooved wheel mounted 011 one stripper roll at the opposite end thereof, a horizontally-disposed worm gear intermeshed with the worm gear on the shaft of the doifer roll and bearing a stud, and a horizontally swinging lever having a slot in one arm receiving the stud on the horizontal gear and also having its other arm enga ed with the circumferentially-grooved wheeI on the stripper roll.

In testimony whereof I have hereunto set my hand in presence of two subscribing witnesses.
